The Lowdown
Alright, let’s break it down.
The next few days are weak and messy. Onshore winds, small swell, not much happening. We’re in a bit of a lull early on, but things start to wake up around Thursday.
Thursday, September 17 – this is the first real pulse. Morning is clean with a light east cross-offshore breeze. Swell is around `5ft` from the south, period around `11 seconds`. It’s got some energy to it – combined energy is `750`. Not huge, but clean and punchy. The afternoon backs off and the tide might mess things up, so hit it early.
Friday, September 18 morning has similar south swell, about `5ft`, but the wind is stronger out of the east-northeast. Still offshore, so it should be alright, but not as clean. Energy is lower at `484`, but still worth a paddle.
Then it drops off. Saturday and Sunday are small and pretty average. Maybe some cross-offshore wind, but nothing worth getting excited about. Early next week is weak – surfable but very ordinary. If you’re desperate, there might be something tiny, but it’s not going to be memorable.
Then there’s a proper dead spell from around the 23rd through the 28th. Small, weak, some glassy moments but very little swell. Beginners might find something to push around on, but everyone else is going to be bored.
Tuesday, September 29 is the big one. Morning has a solid `8ft` of southwest swell with a `11` second period and light east wind, giving you a clean cross-off. Combined energy is `1190` – that’s serious power. This is not for the faint of heart. Only experienced surfers should be out. The afternoon pushes up to `8ft` but picks up a cross-onshore wind and shorter period, so it’ll go lumpy quick. Get your waves in the morning.
After that, it fades out again.
Top picks:
- Thursday morning (Sept 17) – clean, solid, fun.
- Tuesday morning (Sept 29) – the standout, but only for the experts.
Water temp is average for this time of year. Nothing unusual.
That’s it. Keep your eye on that Tuesday swell – it’s the one to wait for.
Rusty out.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
